every Christmas, you have at least one television advert that involve children getting in contact with Santa Claus. Here's an Irish advert from the 1990s that invokes an Enid Blyton-style "the toys come alive" with a little blonde girl contacting Santa through her toy telephone: http://www.youtube.com/watch?v=Gl2u24_d2w0

It's a bit creepy that ad with a small innocent child contacting a strange old man through her toy phone. And WTF do they have that shot of "Santa" loosening his belt?
